INTRODUCTION The aim of the present study was to evaluate the haemodynamic effects of passive leg elevation on the right ventricular function in two groups of patients, one with a normal right ventricular ejection fraction (RVEF) and one with a reduced RVEF. METHODS Twenty coronary patients undergoing elective coronary artery bypass grafting surgery were studied by a RVEF pulmonary artery cat...

BACKGROUND The most sensitive diagnostic criterion of myasthenia gravis is a decrement in the muscular response to repetitive stimulation. The authors hypothesized that myasthenia gravis patients who show a train-of-four ratio (T4/T1) < 0.9 in the preanesthetic period will have increased sensitivity to nondepolarizing neuromuscular blocking agents compared with myasthenia gravis patients with p...

BACKGROUND Development of endotracheal intubation to avoid deleterious effect on hemodynamic responses occurring during laryngoscopy and intubation compelled researchers to venture into alternative measures of airway management with subtle hemodynamic responses. This study was carried out to compare the conditions for laryngeal mask airways LMA insertion with widely used intravenous induction a...

Objective: To compare the effect of a single induction dose of etomidate or ketamine on plasma cortisol levels in children with Tetralogy of Fallot (TOF) undergoing intra-cardiac repair on cardiopulmonary bypass (CPB). Design: A prospective randomized trial. Setting: Cardiac center of a tertiary care hospital. Participants: Thirty children with TOF undergoing intra-cardiac repair on CPB. Interv...

The aim of the study was to examine intraocular pressure (IOP) changes during laparoscopic cholecystectomy performed under either desflurane-thiopental anesthesia or propofol total intravenous anesthesia (TIVA). 36 patients who will undergo elective laparoscopic cholecystectomy were enrolled in the study. The patients were randomly divided into one of two groups: desflurane (Group D, n=18) or p...

The aim of the present study was to compare the perioperative hemodynamics, propofol consumption and recovery profiles of remifentanil and dexmedetomidine when used with air-oxygen and propofol, in order to evaluate a postoperative analgesia strategy and explore undesirable side-effects (nausea, vomiting, shivering). In a prospective randomized double-blind study 50 ASAI-III patients scheduled ...

OBJECTIVE Our purpose was to compare the safety and efficacy of intravaginal misoprostol versus intracervical prostaglandin E2 gel (dinoprostone) for preinduction cervical ripening and induction of labor. STUDY DESIGN Two hundred seventy-six patients with indications for induction of labor and unfavorable cervices were randomly assigned to receive either intravaginal misoprostol or intracervi...

Background And Objectives: Laryngoscopy with or without tracheal intubation amounts to a highly noxious stimulus to the homeostasis of the patient. Many a times under lighter planes of anaesthesia it elicits a defence mechanism in the form of haemodynamic response to stress, which involves activation of adrenocortical system. This study was conducted to compare the effects of oral Clonidine and...

Sir,—Dr Pandit and his colleagues suggest that patients develop a mixed respiratory and metabolic acidosis following a thoracotomy {Brit. J. Anaesth. (1973), 45, 79). However, the results they present do not necessarily support this conclusion. The investigation would have been more convincing if measurements had been made at each stage in all the patients. Incidentally, there are some discrepa...
